seating achines, adapted to cooperate with i an tau. ary feedingmechanism, "such as shown nd described in an application torpatent,Serial lxo. 222,795 filed by lames R. Moi itt August Bl, 1904:. The or ypoint of tion between this n t-echanism and 'cferrcd to, that: theauxiliary lingghladc is extended laterally across the space between andin front of the two needles and the blade acts across the face of thegoods between theueedles, to lay the elastic knitted fabric flat, andwithout wi inkles or distortion, as would be the case were not. anauxiliary feeding device employed to overcome the draw of the fabricincident to its beinlgi guided by the operatm', folding dci ice, etc. Inconnection with this mechanism, [if employ a folding guide to guide andfold in advance of the sewing operation, two pieces of fabric. the toppiece of which-isfknitted or elastic fabric. and which is operated uponby the auxiliary feed, and hasionfe of its edges folded downward andinward upon the second fabric. 'lhe second piece of; fabric has both itsedges folded upward and inward against the top piece of fabric, one ofthe needles passing through the folded edge of the top and bottomfabric, and the opposite needle passing through one thickhess of thebody fabric, and through thfolded portion of the bottom piece, to

45 to n the button hole strip upon the front of a knitted skirt.

, The invention consists in the matters hereinafter described andreferred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which,

g In these drawings, the feeding device or blade it iscarried on thelower end of an arm 2, which is adjustably attached to the lin'aekct 3,clamped on the lower end of the bar or rod 4, which is pivoted on aplate 5, attached to the head of the machine, and connected to theneedle 'bar by means of the connection (3, so that in the upwardmovement of the needle bar, the feeding device The guide used with themachine is provided with a suitable base A, upon which is attached by asuitable screw, (1, the scroll ll, to fold downwardly and inwardly the Ledge of the top pieceof material 10 it having a forwardly projecting armClo keep the folded edge properly directed to the right hand needle. Thelower folding guide l) is provided with a tongue E, as shown in Fig. 5to properly guide. and 'fold a strip of material 11, turning upwardlyand inwardly both edges thereof. 'lhe'outer edge of the fold in thestrip is substantiallybelow the outer edge of the fold in the body pieceof material, although in practice it. is sometimes desirable to have thebottom right hand inwardlyand upwardly turned edge slightly inside theedge of the top folded edge, as shown in Fig. 7, in order that the stripor facing material may be concealed 5 from view when the garment isexposed for sale.

The lower folding guide is provided with a slot F, for the puraose ofthrcadin the strip through the gui e. The upper folding guide Bismounted above the lower foldmg guide D, and has its delivery end 0 infront of the delivery end of the lower guide, thus forn'iing a space forthe operation of the auxiliary feeder. The presser foot G, is providedwith an auxiliary bearing surface of, on tne side under which passes theincreased thickness of material. This is neces sary in a machine of thiskind to hold the fabric in proper position upon the main feed dog tofeed both sides of the seam evenly.

The operation of my device Will be obvious. The strip of material 11 isled through the opening K in the guide D underneath the tongue E. Theguide D tapers toward itsv forward end, and, therefore, as the stripapproaches the forward end of the guide, itwill be folded up over theedges of the tongue E on to the upper surface thereof, as clearlyshowliin Fig. 8. The tongue E is spaced from the sides of the guide D, andtlms forms a guiding recess or passage at -ach side of the uide D, whichcauses the folding above referred to. The tongue E pressesthc stripagainst the bottom portion of the guide, and places, therefore, a slighttension thereon. The top piece of material is led into the scroll B overthe supporting ledge L. Said scroll B has a folding recess 13, whichturns the edge of the material underneath the body portion thereof. Asclearly shown in Fig. 8, the folded edge of the top piece of material ispositioned substantially over the folded edge of the strip, and as thestrip and folded top piece of material pass to the stitching mechanism,they will be stitched together, as shown in, Figs. (3 and 7.

Having thus described my invention, what I claim as new and desire tosecure by Lettors latent, is--- 1. In a two needle machine, a worksupport, stitchforming mechanism including two needles, a main feedingdevice, an auX- iliary feeding device located and operating above saidwork support, a guiding'n'ien'iber having folding recesses at each ofits side edges, a guiding member located above said first named guidingmember and having a folding recess at one side thereof, the foldingrecess in the upper guiding member being substantially .over one of thefolding recesses in the lower guiding member and cooperating thcrowithto direct the folded edges of the material in a line adjacent. one ofsaid needles; substmitially as dcscrila'd.

2. in a two needle machine, a work support, stitch-forming mechanismincluding two needles, a main feeding device, an auxiliary feedingdevice located and operating above said'work support, a guiding memberl'iavmg folding recesses at each of its side edges, a guiding memberlocated above said first named guniling member and having a foldingrecess at one side thereof, thefolding recess in the'u 'mer guidingmember being substantially over one of the folding recesses in the lowerguiding member, and

codpeiating therewith, to direct the folded edges of the material in aline adjacent. one

of said needles, said guiding members being adjust-ably attached to thework support; substantially as described.
